I installed a remote controlled Harbor Breeze Triton fan last weekend. Fan worked great for a week, now suddenly the remote won't control the speed. You can push any of the three speed buttons on the remote but fan only runs at fast speed. When you press a different speed button you can hear the receiver receive the message but the speed doesn't change. Any suggestions on how to correct?

Take down fan, replace in package, return to store. Get money back. If you purchase another remote controlled fan, then repeat.
